Your Kohler Toilet
Your Kohler toilet combines outstanding function, comfort, and
performance with remarkable style and class.
This Kohler toilet was designed to use only 1.4 gallons (5.3 L) of water
for each flush. This ensures that your toilet will provide exceptional
performance that is comparable to our previous 3.5 gallon (13.2 L)
models. Your toilet exceeds ASME performance standards for
low-consumption toilets. It was designed with a large, glazed trapway
to keep waste moving without blockage.
Crafted from a clay mixture that is fired at an intense heat to vitrify
the clay and fuse the glaze, your Kohler toilet is scratch- and
abrasion-resistant. Its surface won’t stain, discolor, rust, or fade. Every
component in your Kohler toilet is specifically designed to increase the
toilet’s useful life.
How to Use This Manual
This manual is designed to help you troubleshoot and repair any
problems that may develop with the operation of the toilet. If a
problem occurs:
Refer to the Troubleshooting section to determine a probable
cause.
Follow the maintenance and repair instructions in this manual to
correct the problem.
Check the Service Parts section to determine the part numbers for
any replacement parts necessary.
Use the information on the back cover of this manual to contact
Kohler Company to order parts, or for help if you cannot correct
the problem.
Care and Cleaning
NOTE: See the special instructions before you clean Artist Edition
products.
Clean the outside surface of your vitreous china toilet with mild soap
and warm water. Wipe the entire surface completely dry with a clean,
soft cloth. You may use soft abrasive cleaners when necessary to clean
your toilet. Do not use strong abrasive cleaners, as they will scratch
and dull the surface. Wipe any splashes of cleaner solutions from
plastic or plated surfaces immediately. Use toilet bowl cleaners on the
inside of the bowl only.
Kohler Co. 3 1044956-5-B
Care and Cleaning (cont.)
If the surface becomes excessively dirty, use a general purpose cleaner
such as: Fantastik
®
All Purpose, Lysol
®
Basin, Tub and Tile Cleaner,
Soft Scrub
®
Multi Purpose, Scrub Free
®
Disinfectant Bathroom Cleaner,
Clorox Clean-Up
®
, Spic and Span Liquid, Comet
®
Liquid Bathroom
Cleaner, Scrubbing Bubbles
®
Bathroom Cleaner, Bar Keeper’s Friend
®
,
or Bon Ami
®
.
Over time, hard water deposits may clog toilet rim holes and
trapways. To clean, use a commercial cleaner that is recommended for
removing hard water deposits. Follow the cleaner manufacturer’s
instructions.
WARNING: Risk of property or product damage. Do not use
in-tank cleaners in your toilet. Products containing chlorine
(calcium hypochlorite) can seriously damage fittings in the tank.
This damage can cause leakage and property damage.
Kohler Company shall not be responsible or liable for any tank fitting
damage caused by the use of cleaners containing chlorine (calcium
hypochlorite).
For Artist Edition toilets: Do not use bristle brushes or abrasive
sponges to clean the surface of your Artist Edition toilet. They will
scratch the decorated surface. Gold and Platinum used on decorative
products are like fine jewelry. Use only warm water to clean, and dry
with a soft cloth. Do not let cleaners sit or soak on Artist Edition
surfaces. Rinse and wipe the toilet surface to prevent soap buildup. If
the surface of your Artist Edition toilet becomes excessively dirty, use
Glass Plus
®
or a liquid dish soap with water.
Toilet Seats: Avoid using abrasive cleaners, detergents, disinfectants or
cleaning products in aerosol cans.
Do not allow abrasive chemicals or cosmetics (such as fingernail polish
or aftershave) to come in contact with the toilet seat, as they can
damage the finish.
Use a soft sponge or cloth to clean the toilet seat. Rinse the seat clean
and dry with a soft towel. Let the seat air dry and ensure that the
hinge area dries completely.
Clean the seat with dishwashing liquid and water or with any of the
following products: Gel Gloss
®
, Scrub Free
®
Mildew Stain Remover,
Formula 409
®
All Purpose Cleaner, Mr. Clean
®
Lemon Fresh, Cinch
®
,
Glass Plus
®
, or Fantastik
®
All Purpose.
Painted wood seats require special care and cleaning. Use only mild a
detergent such as dishwashing soap.

Operation
The vitreous china bowl and tank direct the flushing water flow, and
house the Pressure Lite system.
The vessel contains the complete operating cartridge assembly, and is
the container for the pressurized 1.4 gallons (5.3 L) of water used for
each flush.
The control components consist of the pressure regulator and the air
inducer. These components work with the incoming, pressurized,
supply-line water to provide a regulated pressure flush to the toilet
bowl.
A complete flush cycle is two separate functions.
When the trip lever is operated, the vessel plunger assembly is
pressed, allowing pressurized water to be directed to the bowl for
complete flushing action. As the water level in the vessel drops the
plunger will close, stopping water flow to the bowl.
A checkpoint built into the vessel assembly allows any discharge of
water into the vitreous china tank to drain directly into the bowl.
After flushing, a charge cycle takes place. Supply line water flows into

the vessel through the screen and pressure regulator. The water then
flows across the air inducer, which mixes a small amount of air with
the water, filling the vessel until a pressure of approximately 35 psi (2.5
Kg/cm squared) is reached. The toilet will be ready for the next flush
within 60 to 90 seconds. If the toilet is not ready for the next flush
within that time, please refer to the Troubleshooting section.

Gap Clearance
If the toilet does not activate, the gap between the actuator and
the plunger arm may need to be reset. Make sure the trip lever
handle is installed, and the trip lever nut is tight. This is a
left-hand thread; turn counterclockwise to tighten.
Make sure the water supply is on, and the supply line water has
stopped flowing into the toilet.
Loosen the setscrew. Turn the actuator until there is a 1/16 (2
mm) - 1/8 (3 mm) gap between the actuator and the plunger
arm. Turn the actuator clockwise to increase the gap.
Tighten the setscrew after the gap is properly adjusted.
NOTE: Loss of gap clearance adjustment could cause leakage into
the toilet bowl due to the plunger not sealing properly. This
condition could cause a continual flow of water. If the problem is
not corrected after adjustment, refer to the Troubleshooting section.

Winterizing Your Toilet
Turn off the water.
Drain the tank by flushing. Press the actuator down for
approximately one minute to drain the water from the vessel
assembly.
Disconnect the water supply line to the toilet.
Remove the supply shank, and drain the water from the tank.
Press the actuator one more time, then pull the actuator up to
allow air into the vessel.
Add antifreeze to the toilet bowl water to prevent freezing. Use
recreational-type antifreeze commonly used in campers, motor
homes, and boats.
To restart the toilet, first reconnect the water supply line to the
toilet. Then turn on the water supply, and let the system
pressurize for at least one minute.
Check for leaks, and retighten any leaking connections.
